USCG 3-Year Old
Flotation Manikin
The 3-Year old flotation Manikin was designed, developed and
manufactured under funding from the USCG.  It was tested under
static conditions in the water tank in our facility.  It was tested
dynamically at the David Taylor Naval Basin in Carderock, MD.

The Manikin was developed to test flotation devices under calm and
rough water conditions.  T
he Manikin was developed to test flotation
devices under calm and rough water conditions.  Turning tests were
conducted in the test tank at GESAC, as were tests to measure
hydrodynamic drag coefficients of various dummy segments.  Drag
Coefficients were used in the 3-D simulation model that was also
developed as a part of the project.   Some technical details are
provided below.

The manikin has a rotary potentiometer at each joint, 5 pressure
sensors on the chest at various heights, and a positional gyro in the
chest for a total of 28 channels. An on-board dummy DAS powered by
on-board battery is used to acquire and store data from all data
channels.  The DAS can store data sampled at 100Hz from all
channels for 1 hour.  PC based software supplied with the dummy
allows download of test data after completion of test through a RS-232
port.  

The DAS, all connectors and sensors are watertight.  AVI on the left
panel shows turn test conducted on the manikin.
